Given Mount Kilimanjaro’s proximity to the equator, it experiences distinct dry and wet seasons rather than traditional winter and summer extremes. Consequently, the most favorable time for climbing tends to coincide with the warmest and driest months (refer to Kilimanjaro weather). Safety is paramount, as adverse weather conditions significantly elevate the risks associated with climbing. Rain, mud, snow, ice, and cold can impose considerable strain on the body. Conversely, favorable weather conditions markedly enhance the likelihood of a successful summit attempt. Naturally, these periods also witness increased foot traffic on the mountain. The following table outlines the relative temperature, precipitation, cloud cover, and crowd levels across the calendar months.

For those seeking reduced rainfall and slightly warmer temperatures, January, February, and the first half of March present the best climbing conditions. April and May usher in heavier rains, with a shorter rainy season extending from November to December, though this should minimally disrupt the trek. June to August typically feature clear skies but colder temperatures—ideal for witnessing the wildebeest migration.
